/* ** ** Swift/XRT hardness ratio for Mrk 421. ** Hardness ratio for this file has been calculated by splitting the data at 2.0 keV. ** ** Data taken from the automatic processing at http://www.swift.psu.edu/monitoring/ ** ** When using these data and results in publications, please reference M.C. Stroh & A.D. Falcone 2013, ApJS, 207, 28; arXiv: 1305.4949. ** ** Key: ** ** BinCenter - Center of time bin (MJD). ** BinHW - One-half of the full time bin size (days). ** FracExp - Conversion factor between bin size and observing time. ** Ratio - Source hardness ratio (2.0 - 10.0 keV)/(0.3 - 2.0 keV). ** This is also Rate2/Rate1 from the following columns. ** RatioError - 1 sigma error in the hardness ratio. ** Mode - 0 if in Windowed Timing (WT). ** 1 if in Photon Counting (PC). ** Rate1 - The background subtracted, PSF corrected and pile-up corrected source count rate (cts/s) in the 0.3 - 2.0 keV band. ** RateError1 - 1 sigma error in source count rate (cts/s) in the 0.3 - 2.0 keV band. ** NetRate1 - Background subtracted count rate (cts/s) in the 0.3 - 2.0 keV band. ** NetError1 - Error in the background subtracted count rate (cts/s) in the 0.3 - 2.0 keV band. ** Rate2 - The background subtracted, PSF corrected and pile-up corrected source count rate (cts/s) in the 2.0 - 10.0 keV band. ** RateError2 - 1 sigma error in source count rate (cts/s) in the 2.0 - 10.0 keV band. ** NetRate2 - Background subtracted count rate (cts/s) in the 2.0 - 10.0 keV band. ** NetError2 - Error in the background subtracted count rate (cts/s) in the 2.0 - 10.0 keV band. ** ** ** Upper limits have an error listed as -1.00000. ** */ BinCenter BinHW Ratio RatioError FracExp Mode Rate1 RateError1 NetRate1 NetError1 Rate1 RateError2 NetRate2 NetError2 55625.388643 0.000376 0.09522 0.01427 0.97692 0 9.17301 0.40151 8.18369 0.35817 0.87347 0.12523 0.78019 0.11187 55625.389360 0.000341 0.09617 0.01425 0.98305 0 10.05838 0.44419 8.98280 0.39670 0.96735 0.13682 0.86351 0.12212 55625.390023 0.000321 0.11262 0.01680 0.96396 0 9.15676 0.43405 8.31261 0.39403 1.03122 0.14584 0.93614 0.13239 55625.390671 0.000327 0.09754 0.01465 0.99115 0 10.14150 0.45290 9.07254 0.40515 0.98920 0.14188 0.88468 0.12685 55625.391646 0.000648 0.11228 0.01150 0.98661 0 9.86776 0.31859 8.75242 0.28256 1.10795 0.10764 0.98244 0.09545 55625.392587 0.000292 0.10971 0.01636 1.00000 0 10.24782 0.48461 9.04100 0.42754 1.12426 0.15899 0.99175 0.14025 55625.393229 0.000350 0.09874 0.01487 0.97521 0 9.64639 0.42878 8.59073 0.38184 0.95249 0.13707 0.84749 0.12194 55625.393952 0.000373 0.09005 0.01329 0.96899 0 10.04486 0.42447 8.90630 0.37635 0.90450 0.12792 0.80133 0.11333 55625.394632 0.000307 0.11085 0.01675 0.98113 0 9.70441 0.46281 8.61309 0.41072 1.07571 0.15419 0.95273 0.13661 55625.395344 0.000405 0.08281 0.01252 0.97857 0 9.74317 0.40213 8.62490 0.35599 0.80682 0.11733 0.71534 0.10400 55625.396099 0.000350 0.10541 0.01590 0.98347 0 8.87304 0.41444 7.86896 0.36753 0.93532 0.13412 0.83264 0.11939 55625.396927 0.000477 0.09918 0.01243 0.98609 0 9.81943 0.37122 8.69097 0.32855 0.97392 0.11641 0.86188 0.10301
